Title: Waterproof push-button switch
Inventor: ENDO YASUHIKO
IPC: G03B17/02
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To enhance the assembling property or operation feeling without loosing the waterproof performance by providing an operating member having a fluid passing opening supported movably to a body wall surface on the outside of an elastic waterproof member. SOLUTION: In this push-button switch, since a waterproof packing 20 is arranged on the inside beyond an operating member 16, no waterproofing packing is stuck to a pressing operation surface 16a touching a finger. Since the waterproof packing 20 is not exposed to the outside so that the fear of its damage is minimized, it can be thinned. Thus, when the operating member 16 is pressed, the operation touch is hardly disturbed by the waterproof packing 20, and a sure click feeling can be obtained. Further, since the waterproof packing 20 is nipped and fixed without using an adhesive, it is never peeled even when the pressing operation of the button is repeated. Since the push button part is united as a waterproof button unit 10, and this unit 10 is mounted on a body wall 41, the assembling property can be enhanced.

Title: Plastic optical fiber
Inventor: IKI YOSHIO
IPC: G02B6/00
Filed: 1983-02-14
Abstract: PURPOSE:To improve optical transmission efficiency by using a copolymer of methyl methacrylate and fluorinated ester of methacrylic acid as a cladding component resin. CONSTITUTION:The cladding component resin having >=10 melt flow index value at a spinning temp. is used in a synthetic resin fiber consisting of a methyl methacrylate polymer as a core component and a copolymer of methacrylate ester and fluorinated ester of methacrylate as a cladding component. Not only the increase in the purity of the core component resin but also the improvement in the molecular structural compativility between the core and cladding component resins and the formation of the uniform boundary occuring in the physical ''wetting'' between the core and cladding resins in the stage of spinning are extremely important for an improvement in optical transmission efficiency. The former is achieved by copolymerizing the methacrylate ester having the same molecular structure as that of the core component resin in the compsn. of the cladding component resin and the latter is achieved by using the cladding component resin having specific fluidity at the spinning temp.

IPC: H04N5/74
Filed: 1979-02-28
Abstract: PURPOSE: To obtain the reflection type optical system of a large diameter and wide angle of view which is superior in imaging performance over the entire part of the image plane by disposing a coma flare correcting plate of peripheral light in front of a television projector using only the Schmidt correcting plate.  
     CONSTITUTION: An extremely bright optical system of wide angle of view is demanded for television projectors and when a reflection type optical system using a Schmidt correcting plate is used in order to obtain a large diameter, the degradation in imaging performance of the periphery of image plane is large and the decrease in resolving power is considerable of the portions closer to the periphery because no considerations are paid for out-of-axis light. So, a correcting plate 7 which corrects coma flare of out-of-axis light is disposed in front of the Schmidt correcting plate 1. r 6  of the correcting plate 7 is plane, r 6  aspherical face and selecting the aspherical face coefficient to the specified value lets only the peripheral luminous flux become over without any change in the aberrations of the central luminous flux, thus permitting the improvement of the focusing characteristic of the luminous flux as a whole.

Title: Blank holder and knockout mechanism in circular drawing press die and their method
Inventor: IWATA YUKIO
IPC: B21D24/04
Filed: 1989-02-03
Abstract: PURPOSE:To simplify a blank holder and a knockout mechanism in a drawing press by performing the actions of the blank holder and the knockout through the air pressure of an air cushion in a die. CONSTITUTION:The external peripheral part of a work S is inserted and held by the fall of an upper fixed drawing punch 1 between a blank holder ring 2 and a lower fixed drawing die 7 to hold the work S. By this method, in a drawing time by the punch 1 and the die 7, flaws are prevented from being generated in the work S. In other words, the blank holder ring 2 abuts with the die 7, then, is pushed into the upper part of an annular air pressure room 6 as a fixed pushdown force is received by the air pressure in an annular air pressure room 6. In this time, the punch 1 is fitted into the die 7 and the work S is pressed and drawn between the knockout 8 and the punch 1. When a rising stroke is started, the knockout 8 is pushed up by the air pressure of the air pressure room 10 with the rise of the punch 1 to push out the drawn work S to the upper part of the die 7. Besides, the blank holder ring 2 is pushed out by the air pressure in the air pressure room 6 and returned to the original state.
